The ratio R of the densities of etchable fission tracks in a mineral and co-irradiated external
detector is shown to depend on the length ratios of the latent (Lf/Lf′) and etched fission …

An apatite fission track study of crystalline rocks underlying sedimentary basins in
northeastern Brazil indicate that crustal blocks that occur on opposite sides of a geological …

Abstract LA–ICP-MS (laser ablation–inductively coupled plasma-mass spectrometry) has the
potential to measure uranium concentration for fission-track (FT) chronometry as an …

Deep boreholes serve as natural laboratories for testing thermochronometers under
geological conditions. The Kontinentale Tiefbohrung (KTB) is an interesting candidate …

The primary goal of this qualitative case study was to investigate the nature of holistic
thinking in the context of an asynchronous computer conference. Holistic thinking was …

The fission-track method (FTM) in apatite was applied to 45 samples collected in the Serra
da Mantiqueira (Mantiqueira mountain range), the Serra do Mar (Mar mountain range) …

Neste trabalho foram associadas às idades de traços de fissão em apatitas (TFA) e idades
(U-Th)/He em perfil vertical na porção centro-sul da Serra do Mar (Sudeste/Brasil), o qual foi …

This paper presents a simple method for determining the spontaneous fission decay
constant (λf) of 238U using a combination of CR-39 and diallyl phthalate (DAP) plates as …

Combined methods of fission track (FTM) and U–Pb in situ zircon dating were applied to
sedimentary samples from the Vale do Rio do Peixe Formation, Bauru Basin, Brazil. Detrital …

Fission track thermochronology (FTT) has been applied for decades to quantify rates and
timing of processes in the shallow crust. The most widely used approach is the external …
